On-line Version of the PA-100 Enterprise Registration Form

Pennsylvania Open for Business allows users to register an enterprise electronically with the Commonwealth in two ways; an online interactive interview and an on-line version of the PA-100 Enterprise Registration Form.

The PA On-line Business Tax Registration (PA-100) will assist you in completing all applicable sections that pertain to your enterprise's individual registration needs. The On-line PA-100 may be used to register a new enterprise, add additional taxes or services, or to register a new enterprise that is acquiring all or part of an existing enterprise. 

Note: If you already have a Sales, Use, and/or Employer Withholding or Unemployment Compensation tax account, and are attempting to register to file and pay business taxes electronically via the internet, please visit our e-Tides homepage.

If you need to register with the PA Department of State, please use the Online Business Registration Interview (OBRI) available at PA Open for Business.

The On-line PA-100 can also be used to register for other taxes.  However, these registrations must be printed and mailed upon completion of the online process.  See "About On-line PA-100 " for information about other taxes. 

NOTE:  To use the On-line PA-100 you must have the proper browser with 128-bit encryption. If you need to upgrade your browser, click on the Security link.
